I have read a book with a very similar story line.the main difference being that kids were the survivors and their parents were after them.Can anyone tell me the title and author of this book as i cannot remember and its driving me nuts.I think it was an English writer and was set in england.Please help. In the book the kids tried to reestablish society. But of course it got a bit lord of the flies in places someone out there must be able to help me out with this. by the way film was great.was very surprised to see christopher Ecclestone in this film.Was a bit disappointed that there wasn't more famous/familiar faces in this movie
